MOUNTING FOR CULTIVATOR-BLADES.

Application filed. April 10, 1911.

To aZZwhom it may concern:

Be it known that I, LELAND WILLIS, a citizen of the United States,residing in Grenloch, New Jersey, have invented cer- 5 tain Improvementsin Mountings for Cultivator-Blades, &c., of which the following is aspecification.

My invention relates to devices employed for mounting cultivator blades,hoes, or shovels upon the frame of the machine so as to permit ofvertical and lateral adjust ment of the same, the object of my inventionbeing to simplify and cheapen the devices employed for this purpose.This object I attain in the manner hereinafter set forth, referencebeing had to the accompanving drawing, in which- Figure l is a verticallongitudinal section of a cultivator blade mounting constructed inaccordance with my invention; Fig. 2 is a horizontal section of the sameon the line aa, Fig. 1; and Fig. 8 is a view similar to Fig. 2, butillustrating a modification of the invention.

In the drawing, 1 represents a cultivator blade or, it may be a hoe orshovel, depending upon the type of machine to which my invention isapplied. This blade is mounted upon a hanger 2 depending from the fixed1 0 frame of the machine to which it is pivoted by means of a pin orbolt 4, being retained in position by means of a wooden or other brakepin 5 engaging the frame and hanger in the usual manner and serving topermit .1: the hanger and the blade carried thereby to yield when it issubjected to abnormal pressure.

Between the blade and the front of the hanger 2 is interposed a block 6whose rear face is curved and fits the correspondingly curved front faceof the hanger so as to permit of the swinging of the blade laterally toone side or the other, as may be desired. \Jlhe blade 1 is secured inplace by means 45 of a bolt 3 which passes through central openings inthe blade 1 and block 6, through the slotted lower portion of the hanger2 and through a washer 7 bearing upon the rear face of said slottedlower portion of the hanger, the rear end of the bolt being threaded forthe reception of the nut 9 which bears against the outer face of thewasher 7, the latter being curved and the washer having an elongatedslot which permits of a diagonal disposition of the bolt 3,

the slotted lower portion of the hanger and serves to prevent lateralmovement of the washer in respect thereto. The slotted lower portion ofthe hanger 2 also permits of vertical adjustment of the blade to permitdifferent depths of penetration of the same.

My invention provides for the mounting of a blade with the use of aminimum number of parts, and by causing the bolt 3 to engage directlywith the blade 1 avoid the necessity for providing the back of the samewith an attacking yoke and thereby not only reduce the expense of themounting but also overcome the inconvenience arising from its use, theliability of breakage of this yoke compelling the farmer to keep on handan extra supply of blades in order to replace blades and keep themachine in proper operative condition.

A mounting such as that constituting the subject of my invention has noparts which are susceptible to breakage under ordinary conditions of useof the machine.

Instead of providing the washer 7 with a curved outer face and astraight inner face these conditions may be reversed, as shown in Fig.3, the outer face of the washer being flat and the inner face curved forbearing upon the beveled rear faces of the side members of the slottedlower portion of the hanger 2, in which case the slotting of the washerwill not be necessary. The construc tion shown in Figs. 1 and 2-, is,however, preferred.

I claim:

1. The combination of the depending hanger having a slotted lowerportion. the blade, a block disconnected from the blade but interposedbetween the latter and the slotted lower portion of the hanger andhaving a curved rear face bearing upon the correspondingly curved frontface of said hanger, a bolt adapted to an opening in the blade and blockand passing through the slotted portion of the hanger, a nut on saidbolt, and a washer interposed between said nut and the rear face of thehanger, said washer also having a curved face.

2. The combination of the depending hanger having a slotted lowerportion, the blade, a block disconnected from the blade but interposedbetween the latter and the washer having a curved outer face and a 1slotted lower portion of the hanger and havtransverse slot for thereception of the bolt. ing a curved rear face bearing upon the cor- Intestimony whereof, I have signed my respondingly curved front face ofsaid name to this specification in the presence of hunger, a boltadapted to an opening in the two subscribing witnesses.
